Hello i live in WA state i got pulled over friday night for not using a turn signal when i know i did. The cop pulled me over and arrested me for having a suspended license and suspected me of being under the influence even when i was'nt. The cop pulled out my passenger and he had around what appeared to be a ounce of weed or so in his pocket. this time im in the back of the cop car. and they find a backpack in my car ask if its mine and i was'nt even aware it was in my car. they found 100 ecstasy pills mushrooms and a scale and baggies All in that backpack along with 50 other pills in my car.. The kids that were in my car said that the backpack was in my car when they got in it. the cops arrested me and put me into the holding cell after impounding my car and taking my cell phone. They released me on account that i would call them on monday and do some informant work for the taskforce. I'm trying to avoid this considering my life would be on the line for being a snitch. Please Please help with any advice or personal expeirnces or recommendations on what i could do. I'm 19 this is my first offense but i also found out to of the kids in my car were minors.. Thank you for your time and possible advice.What is the name of your state (only U.S. law)?
